The Great Rail Shift

Convergence between legacy infrastructure and stablecoin rails.

Stablecoins moved roughly $33 trillion in gross transaction volume against a cross-border payments market estimated at more than $1 quadrillion a year.

“At this point, moving money is a solved problem. Everyone can do that, be that in traditional finance or now in the stablecoin space. But what nobody has really cracked yet, from my perspective, is letting enterprise configure the rules about how they move money.”
